HOWARD K. DE WOLF, OF WARREN, RHODE ISLAND.

SODA-TUMBLER.

Application filed January 28, 1909.

To all whom it may concern:

Be it known that I, HOWARD K. DE Tom, a citizen of the United States, residing at \Varren, in the county of Bristol and State of Rhode Island, have invented certain new and useful Improvements in Soda-Tumblers, of which the following is a specification.

My invention relates to that class of drinking glasses known as soda tumblers.

It is well known that the syrups used in compounding a glass of commercial soda exceeds many fold the value of the carbonized liquid combined therewith to concoct a glass of soda. The amount of waste by dispensers constitutes a serious aggregate when the amount of soda in a single glass exceeds a predetermined ratio of the entire contents of the glass.

It is the purpose of this invention to remedy the indicated trouble by providing a tumbler which shall, by its construction, indicate the desired amount of syrup; and which shall be effective for its purpose by making the indication visible without elevating the tumbler to a lane horizontal to the eye; and which shal be inexpensive to construct.

To the above ends essentially my invention consists in the novel construction and combination of parts hereinafter described, and illustrated in the accompanying drawings, wherein,

Figure 1 is a side elevation of a glass embodying my invention, and Fig. 2, central vertical section of the same.

My novel tumbler has a preferably tapering transparent body portion, A, provided Specification of Letters Patent.

Patented June 15, 1909.

Serial No. 474,710.

about a quarter of the distance from the bottom, B, of the tumbler with a transparent hollow or concavo convex annular rib, C, producing by its interior concave surface an annular channel or recess, D, extending outwardly beyond the plane of the exterior face of the body, A.

In filling the tumbler, the syrup, which is nearly always a colored liquid, is poured into the vessel until the liquid reaches and enters the recess, D, whereupon its presence at that height is brought to the attention of the dispenser, while the tumbler is in its natural position in a plane below the eye of the operator, by reason of the fact that the color of the liquid in the recess is imparted to the rib, C, at a point upon the tumbler exterior and projecting therefrom. The comparatively inexpensive carbonated liquid or soda may then be introduced into the tumbler ad libitum.

By the described device it will be seen that the dispenser can concoct the mixture with uplusual speed and accuracy and ecconomica y.

WVhat I claim is,

In a soda tumbler, the combination with a body, of a transparent external annular rib integral wit-h the body and provided with an internal annular recess extending beyond the plane of the exterior face of the body.

In testimony whereof I have affixed my signature in presence of two witnesses.
